CAN-GAPPING MACHINE. v

Application filed April 3-, 1926. Serial No. 99,650.

This invention relates to acan capping machine, the general object ofthe invention being to provide means for placing friction caps on cans,with means whereby the device can be used with different sizes eralviews, and in which Figure 1 is an elevation, with parts in section, ofthe device. 7 v

Figure 2 is a view of the piston, with parts insection.

c Figure 3 is a view of the split-spring ring usedwith the piston.

In thse views,l indicates the base of thc device and 2 indicates theupright connected with thebase and having a horizontal part 2 which isprovided with the vertically ar ranged bore 3 which is of two diametersto receive the stem 4 of the piston 5 and the spring 6 which surroundsthe upper part of thestem. An arm 7 extends upwardly from the upperpartof the upright and has a tapered hole 8 therein which receivesthetapered end of a handle 9 which has a hole therein to receive theupper end of the stem 4, the stem being pivotally arranged in the holeby means of the pin 10. The piston 5 is formed with the reduced lowerpart which is provided with the annular groove 11 in which fits a splitspring ring 12. This reduced part enters the cap, shown at B', with theupper edge of the cap engaging the under face of the large part of thepiston so that this part tends to force the edge against the top of thecan. The spring ring 12 will engage the cap and hold it in place on thepiston, and by making this ring of spring metal, it will act to holdcaps of different sizes on the piston so that the machine can be usedforcapping cans of different sizes.

The can A to be capped is placed on the base 1 in front of the upright,2 and under the piston, 'thecap B having been placed on the piston, asshown in dotted lines in Figure 1. Then the handle isdepressed. whichforces the piston downwardly so that the cap 1s pushed into the can topand thus the can will be sealed. The spring will return-the i parts toraised position as soon as pressure is removed from the handle. ringwill hold the cover squarely on the piston, so that it'will nottilt'when being forced into the mouth of the ca The device will insertthe cap without injuring either the can or the cap.

. It is thought from the foregoing description-that the advantages andnovel features 7 of my invention will be readily apparent. i I deslre itto be understood that I may make changes in the construction and in thecombination and arrangement of the sev-' eral parts, provided that suchchanges fall within the scope of the appended claims. ,l Vhat I claim isr p I 1. A can capping machine comprising a base, an upright thereonhaving a horizontal upper part which has a vertically arranged holetherein, a stem passing through the hole, a piston on the lower. end ofthe stem formed with a lower reduced part to receive a can cap, anupwardly extending arm on the upright having a tapered horizontal holetherein, a handlehaving a tapered end fitting in the hole for movablyconnecting the handle with'the arm, means for pivoting 6O The spring thehandle to the stem and a spring onthe stem betweenthe handle and a partof the upright for holding the piston in raised position. i

2. In a can capping machine, a piston or chuck having a reduced part forentering a 1 can cap, said part having an annular groove therein and asplit spring'ring seated inthe groove for causing the said piston orchuck to fit can caps'of different sizes.

' In testimony whereof I afiix my signature. SILVIO PETREGCA.
